What type of pencil graphite would be used to light up an LED light the brightest?
Materials List
1. A piece of paper 2. A 9v battery 3. 4 different pencil graphite 4. A small LED light 5. Alligator clips
Procdure
1. Draw 2 different dark lines on paper 2. Draw a + sign of one of the lines 3. Draw a - sign of the other line 4. Attach the LED light to both lines 5.Take the alligator clips and link it with the 9v battery 6. Attach the + clip to the positive clip to the positive 7. Repeat step 6 but with the -
Variables
Independent Variable: The graphite of the pencil.
Dependent Variable: The brightness of the light.
Variables That Need To Be Controlled: The paper it self.
Hypothesis
My hypothesis is the higher the pencil # the brighter the light is.

General Plan
My general plan is to take a piece of paper and draw a two lines and to poke an led light to the positive and negative charge and connect alligator clips to the positive and negative on a 9 volt battery and then put the other end of the alligator clip and then to light the led light and when I do the two lines I'm going to do 4 diffrent trials with a #1 pencil and a #2 pencil and with a #3 pencil and a#4 pencil.

3. Information: The information I had gained using this website is my citation’s in order to do this paper.
Detailed Procedure
Fist i had took two alligator clips and connect them together. Also I had taking a 9v battery and take graphite on a piece of paper and then connect the positive clip to the positive clip to the 9v battery and do the same with the negative then take an LED light and connect it to the end of the circuit and connect and do it with the paper to the other side.
